Hosi ya Suction imagwiritsidwa ntchito makamaka pa mkono wokoka wa Trailing Suction Hopper Dredger (TSHD) kapena makwerero odulira a Cutter Suction Dredger (CSD). Poyerekeza ndi mahosi otulutsira madzi, mahosi otulutsira madzi amatha kupirira kupsinjika koipa komanso kupsinjika kwabwino, ndipo amatha kugwira ntchito mosalekeza pansi pa mikhalidwe yopindika. Ndi mahosi ofunikira a rabara kwa odulira madzi.

Zinthu zazikulu za Suction hose ndi kukana kuwonongeka, kukana nyengo, komanso kusinthasintha.

Kawirikawiri mphamvu yogwira ntchito ya Suction Hopes ndi -0.1 MPa, ndipo mphamvu yoyesera ndi -0.08 MPa. Ma Suction Hopes okhala ndi zofunikira zapadera kapena zosinthidwa, monga zomwe zimatha kupirira kupsinjika kuyambira -0.1 MPa mpaka 0.5 MPa, amapezekanso. Ma Suction Hopes ndi oyenera kutentha kozungulira kuyambira -20℃ mpaka 50℃, ndipo ndi oyenera kunyamula madzi osakaniza (kapena madzi a m'nyanja), matope, matope, dongo ndi mchenga, zomwe zimakhala ndi mphamvu yokoka kuyambira 1.0 g/cm³ mpaka 2.0 g/cm³.

Mapaipi opopera a CDSR amatsatira zofunikira za muyezo wapadziko lonse wa ISO28017-2018 ndi muyezo wa Unduna wa Zamankhwala ku China HG/T2490-2011, ndipo amathanso kukwaniritsa zofunikira zapamwamba komanso zomveka bwino kuchokera kwa makasitomala.

Malinga ndi mikhalidwe yosiyanasiyana yogwirira ntchito, nthawi zambiri pali mitundu inayi ya Mapayipi Opopera: Mapayipi Opopera okhala ndi Nipple Yachitsulo, Mapayipi Opopera okhala ndi Sandwich Flange, Mapayipi Opopera Otetezedwa ndi Armored Steel Cone ndi Mapayipi a Segment Steel Cone.
